概括

尽管采取了预防措施,但B组链球菌 (GBS) 仍然对新生儿构成重大威胁. 在欧洲协调查和产后抗生素预防 (IAP) 对于减少早期发病的GBS疾病至关重要.

科学领域:

新生儿传染病新生儿传染病
疫苗学疫苗学疫苗学
微生物学微生物学

背景情况:

在欧洲和美国,B组链球菌 (GBS) 导致了显著的新生儿发病率和死亡率.
建议进行产内抗生素预防 (IAP),但不能消除新生儿GBS感染.
欧洲DEVANI计划调查了新生儿GBS感染的负担和特征.

研究的目的:

评估欧洲新生儿GBS感染负担.
在被殖民的孕妇和他们的婴儿中鉴定GBS菌株的特征.
评估当前GBS预防策略的有效性.

主要方法:

包括来自欧洲八个国家的1083名孕妇,具有GBS阳性培养.
通过标准化问卷收集临床产科数据.
使用血清学和分子方法对GBS菌株进行了鉴定.

主要成果:

13.4%的GBS携带者有早期发病 (EOD) 的其他产科风险因素.
最常见的GBS囊类型 (Ia,Ib,II,III,V) 占运输量的93%左右.
虽然77.8%接受了IAP,但只有49.5%接受了适当的预防;9名新生儿患有GBS EOD.

结论:

为了降低EOD率,需要在欧洲协调GBS查和IAP协议.
这项研究的流行病学数据对于开发有效的GBS疫苗至关重要.
需要有针对性的干预措施和改进的预防策略来保护新生儿免受GBS感染.

Transcytosis of IgG

Transcytosis of IgG

Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...
